ABSTRACT:
A computer system for executing a binary image conversion system which converts instructions from a instruction set of a first, non native computer system to a second, different native computer system, includes an run-time system which in response to a non-native image of an application program written for a non-native instruction set provides an native instruction or a native instruction routine. The run-time system collects profile data in response to execution of the native instructions to determine execution characteristics of the non-native instruction. Thereafter, the non-native instructions and the profile statistics are fed to a binary translator operating in a background mode and which is responsive to the profile data generated by the run-time system to form a translated native image. The run-time system and the binary translator are under the control of a server process. The non-native image is executed in two different environments with first portion executed as an interpreted image and remaining portions as a translated image. The run-time system includes an interpreter which is capable of handling condition codes corresponding to the non-native architecture. A technique is also provided to jacket calls between the two execution environments and to support object based services. Preferred techniques are also provided to determine interprocedural translation units. Further, intermixed translation/optimization techniques are discussed.
